After tripping an opponent, when they try to get up and u get an attack of opportunity on them can you attempt to trip them again with your attack of opportunity? (Any official proof from the CRB)
The AoO takes place before the triggering action, so they are still prone and cannot be tripped. On the up side, they are prone, and hence easier to hit.
Edit
From the CRB faq:
Trip: When a prone character stands up and provokes an attack of opportunity, can I use that attack to trip the character again?
No. The attack of opportunity is triggered before the action that triggered it is resolved. In this case, the target is still prone when the attack of opportunity occurs (and you get the normal bonuses when making such an attack). Since the trip combat maneuver does not prevent the target's action, the target then stands up.
